Washington County deputies said Young could face criminal charges even though she was in the middle of a medical emergency during the crash. Detectives are investigating whether she was taking medication, and whether that played a role in the crash.

“If a person has a medical condition it doesn’t necessarily mean they’re not responsible for any of their actions after that point,” said Washington County Sheriff's Office Sgt. Bob Ray. “They need to make sure they’re following everything they’re supposed to be doing to be healthy and keep other people safe at the same time.”

Young’s mother said her daughter has not been taking medications for her seizures, but she has been taking medications for depression and anxiety.

Young was arrested on a DUII charge in 2008, but her mother said no alcohol was involved and blamed her medications.

Young pleaded no contest and entered a diversion program. The charge was later dropped.

Investigators said it could take several more days to decide whether to pursue criminal charges related to Tuesday's crash.

“I really feel for the person who was driving the car,” said Nikki Hurtado, who was placing flowers at the roadside memorial for McGregor Wednesday. “I don’t know what happened and why she jumped the curb and struck him.”
